SPECIFICATION forming part of Letters Patent No. 595,390, dated December 14, 1897.

Application led .Tuly 11, 1896.

T0 all whom, t may concern,.-

Be it known that I, CHARLES O. HEGGEM, a citizen of the United States, and a resident of Massillon, county of Stark, State of Ohio, have invented a new and useful Improvement in Pneumatic Straw-Stackers, of which the following `is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to certain improvements in pneumatic straw-stackers; and it consists ot' certain features of construction and combination of parts, as will be hereinafter described and claimed.

Figure 1 of the drawings is a view in perspective from left front of a fragment of the rear portion of a thresher-frame and the front portion of the discharge-pipe. Fig. 2 is a crosssection through the pipe at rear end of the elbow. Fig. 3 is a side view of sheave-support. Fig. 4. is a longitudinal section of the discharge-pipe and discharger and fragmentof .thresher-frame and cross-section of turn-table. Fig. 5 is a cross-section at front end of the rear section. Fig. 6 is a cross-Section of front end of front telescoping section. Fig. 7 is a side view of the discharge-pipe with front portion cut away and cross-section cut out for the purpose of shortening the view. Fig-8 is a side view of the rear portion of the threshing-machine frame. Fig. 9 is a cross-section through discharge-pipe on line e 2,Fig. 7. Fig. 10 is a longitudinal section of a fragment of the discharge-pipe and hood, showin g the manner of connecting the hood to the body of the pipe.

Fig. 11 is a plan view of oscillating mechanism and turn-table. Fig. 12 is a side view of gearing. Fig. 13'is a side view of clutch-trip. Fig. 14 is a longitudinal section of4 trip. Fig. 15 is a portion of detail of shifter.

In the drawings, A denotes a rear end por- Serial N0. 598,795. (No model.)

or fan-blades C are secured. On the top of said hub is provided a deflecting cap or plate C2, by which the straw and chaif are deflected to the blades and thereby thrown into the discharge-pipe.

The discharger and the gearing to drive it have been described in my application tiled April 27, 1896, Serial No. 589,193.

D denotes a platform which is secured to the rear end of the thresher-frame at a point above the fan or discharger casing B. A metal plate F. is supported on said platform and is provided with a central aperture surrounded by annular grooves or seats c, in which are placed antifriction-balls e. On the balls e is placed a turn-table F, havingin its upper and lower faces about a center aperture grooves I f and g and about its periphery a series ot' cogs or teeth h. The turn-table is provided with a downwardly-projecting short sleevej, which projects into the central aperture in the plate E, and also with an upwardly-projecting short sleeve 7a. Antifriction-balls c'are placed'in groove f, and placed over them is a binding-plate G., supported on sleeves or spools Z, through which bolts m are passedinto the plate E to hold the plate G in position.

To the sleeve .lo is secured an elbow-section 1 of the discharge-pipe L. Another section 2 has its lower end connected with the fan-box B, while its upper' end projects upwardly through the openings in the platform and plate E and almost connects with the lower end of the section. The adjacent ends of these two sections of the discharge-pipe are surrounded by the sleeve j of the turn-table, which tightly engages the ends and forms an air-tight joint.

M denotes a band or ring which is bolted to the upper end of the sleeve and from which project rearwardly arms n. A pipe-section 3 has an elbow o, which passes down over the elbow of Section 7 and is connected to the arms n by the arm p, so as to have a swinging movement therewith. The arms p may be connected with section 3 in any suitablemanner-as, for instance, by a ring or band T, which is cast integral with the arms p. Supporting-standards P are secured .to the ring M, one on each side of the dischargepipe, the upper end of Isaid standards being securedtogether by a pin q, on which is jour- ICO naled a sheave-wheel yr. Braceebars s are attached to the pin q at their upper ends, and their lower ends are secured to lugs t, projected from the band M. A worm Q is journaled to the bars s and engages a worm-wheel u, secured to the end of a winding-drum r, journaled to the brace-bars s. This worm is provided with a crank w. A cord R connects the drum o with the hoisting-pulley S, which will be explained farther on.

The discharge-pipe L is composed of sections l, 2, 3, and 4, the two, 3 and 4, being known as telescoping sections-that is, section 4 is adapted to be drawn over section 3 to shorten or lengthen the pipe. About section 3 is provided a cage or frame for the sup port of the pulleys w and a: and chain-wheels a and a7, composed of the bands T and U, having upwardly-projected lug c', that support chain-wheels a and a7 and the anglebars V. At the outer end of section 4 is provided a rotatable hood XV. About the inner end of the hood-section is placed a band of an gle-iron Z,that forms a track for the grooved wheels d, by which the hood is supported in a rotatable connection with section 4 of the pipe. At one side ofthe band X is provided a frame X', that forms a support for the sheave-wheels a2, and the grooved wheels d are supported on pins, as a3, in brackets a4, secured to band X.

To lengthen or shorten the pipe, a sprocketwheel a5 is supported on pin a, secured to the ring U, and a similar wheel a7 is mounted on shaft a8, journaled in lugs a9 on band T. A crank al() is secured on shaft a8. A chain b is placed about the wheels a5 and a7 and secured to ring b2 on the inner end of section 4.

By turning the crank alo section 4 of the discharge-pipe may be drawn onto or off of section 3, and to take up or let out the rope A', by which the hood is moved up or down, an equaliZing-bar A2 is secured to ring T on the inner end of section 3 of the pipe, having at its end portions sheave-wheels b3. The rope A is rove about the pulleys b3 in the equalizer-bar A2 and the pulley c on band U. The ends of the rope are then secured to the hood. The middle portion of the rope is passed about a pin b4, secured to band b2 on the inner or front end of section 4 of the discharge-pipe. In operation section 4 may be moved forward or back without affecting the position of the hood XV, and the position of the pipe may be changed or moved up or down to give direction to the flow of straw by drawing the lower side of the rope A' forward or back, as the case may be. To rotate the hood to a desired position to discharge the straw to either side, a rope, as A3, is secured about the hood and the pulleys a2 and passed forward and secured, as shown at b5. By drawing on either end of this rope the hood may be rotated a distance to either side of the discharge-pipe for the purpose hereinbefore stated. To raise or lower the outer or rear end of the discharge-pipe, the crank yw and drum o may be turned to wind or unwind the rope R to move the pulley7 S forward or back to take up or let out the rope A4, on which the outer end of the pipe is Supported, one end of said rope secured to band X on the rear end of section 4. The other end is passed about the sheaves S and w and secured lo band b2, that the telescoping sections may be operated without moving the pipe vertically. The supporting-arms@ and n, being pivotally secured together, form a hinged support for the front end of section 3. Section l, or the elbow, is formed of two telescoping parts, the one sliding over the other to provide for the vertical adjustment of sections 3 and 4. To rotate the table to oscillate the discharge-pipe about its pivotal connection with the body of the threshing-machine, a worm A4 is provided to engage the teeth 7L on the periphery of the turn-table F. To oscillate the discharge-pipe by hand, a crank b is mounted on the drivingshaft b7, journaled in boxes U3 on the platform E. By turning said shaft by the crank provided thereon the worm engagement with the teeth on the turn-table will cause the table to be rotated to osciliate the dischargepipe or to hold it over the body of the machine for the purpose of convenience in transportation or storage.

To automatically oseillate the rear end of the stacker or discharge-pipe, I have secured to shaft b7 gear-wheels d' and cl2, and on the driving-shaft B', which is journaled in boxes d3, are loosely mounted gear-wheels d' and d5, one of which, (Z5, engages wheel d2 on shaft b?, the other engaging an intermediate wheel d6, journaled on a stud (Z7, said wheel d engaging wheel CZ'. On shaft B', between the wheels d4 d5, is a clutch B2, secured to said shaft in a sliding relation by a spline or other device, and on the inner faces of the wheels d" d5 are provided corresponding clutches d8 (Z9.

On the end of shaft B is mounted a gearwheel d10, that engages a similar drivin g-wheel CP2 on shaft B3, journaled in boxes c' c2. On the end of said shaft is mounted a pulley e113, which may have a belt connection with a similar pulley on the threshing-machine. Adjacent to the clutch is pivotally secured an operating-lever d, having prongs e115, that embrace the clutch B2 between the clutchheads. The lever d1' extends over the segmental ring B4, on which are provided stops d1, adjustable on said ring, that engage the end portion of the lever du. On the under side of the lever are provided lugs d, that support a latch k', having a conical or truncated head 752. On the body of the latch 7a' is provided a coiled spring 7c3, the energy of which is exerted to throw the latch out. The

object of the latch and spring is to throw the lever, so as to secure the engagement of the clutch.

In operation the pulley dw, having a belt engagement with similar pulley on the threshing -1nachine, will continuously rotate the A4, rotating the table F, will carry one of the stops or blocks d against the sides of the end portion of the lever C114. The block oll will move the lever over to one side until the block d passes the end of the lever, which will then be driven by the spring k3, driving the conical head k2 down on the side of the stake 7a4 to complete the throw of the lever to carry the clutch into engagement with one of the wheels d4 d5, thereby reversing the movement of the shaftl, turn-table, and discharge-pipe. This movement will continue until-the other block C116 engages the other side of the vlever (114 and reverses the movement of the parts. Alatch, as x', is supported on shaft 57 and secured against a sliding movement on said shaft by collar 002. The latch is adapted to be dropped between the heads of the clutch B2 to hold the clutch from engagement with the wheels d4 d5 when the machine is operated by hand.

In operation the straw and chaff will fall on 'the discharger or blower, (as the fan and its chamber or box may be properly termed,)

placed, as it is, obliquely to the body of the threshe'r. The straw and chaff will then be discharged through discharge pipe to the place of stacking. y

Having thus fully described my invention, what I claim`is l. VIna pneumatic straw-stacker, the combination of the hood W, band Z, that forms a track for grooved wheels d, band X that supports said wheels, and grooved wheels cl, Aby which the hood is held in revoluble relation with the discharge-pipe.

2. In a pneumatic straw-stacker, the combination of a discharge-pipe having a telescoping section, the equalizer-bar A2 secured to the forward section of the discharge-pipe and having sheave-wheels b3 at its ends, wheel on the telescoping section, rope A', rove about said wheels and a rotatable hood W to which the rope is attached.

3. In combination in a pneumatic strawstacker, al discharge-pipe having a telescoping section,thc rope A4 having its ends secured to the rear end portions of the discharge-pipe and telescoping section, the. sheaves w, S, r,

rope R, and a winding mechanism whereby the rear end of said lowered.

4. In a pneumatic straw-stacker, having a telescoping section, rotatable hood W, carried by said section, rope A and equalizer A2, to operate the hood W, and ropes A4 and R, chain-Wheels A5, a7 and chain b whereby the discharge-pipe may be lengthened or shortpipe may be raised or ened without affecting the hood or moving the pipe vertically.

In testimony whereof I have hereunto set my hand this 30th dayof June, A. D. 1896.
